How do you relieve the fuel pressure on a scion tc?

To relieve the fuel pressure on a Scion TC, first, locate the fuel pump fuse in the fuse box and remove it while the engine is running to stall the engine. Once the engine is off, disconnect the fuel pump relay for extra safety. Next, locate the fuel pressure relief valve, typically on the fuel rail, and use a rag to catch any fuel that may spray out when you press the valve's pin to release the pressure. Finally, ensure to properly reconnect all components after the pressure has been relieved.
